Appleton Tower and Wilkie subnets and VLANs

Printer-friendly versionPrinter-friendly version

The School of Informatics has some 40 or so different IP subnets in use.

Each of these serves a particular purpose but, for users in Appleton Tower and Wilkie, the six most important subnets are:

Subnet Purpose
129.215.2.0/23 DICE desktop machines in student labs
129.215.199.0/25 Self-managed machines in staff offices using static IP addresses
129.215.199.128/25 Self-managed machines in staff offices using dynamically-assigned IP addresses
129.215.212.0/24 DICE desktop machines, and Windows managed desktop machines, in staff offices
192.168.105.0/24 Self-managed machines in open areas (using both dynamically-assigned and static IP addresses)

Each of these subnets is carried on a particular VLAN - i.e. a virtual 'piece of ethernet'. The mapping of the above subnets to VLANs is:

Subnet VLAN name VLAN number
129.215.2.0/23 ATLABS 2
129.215.199.0/25 R 199
129.215.199.128/25 ATDHCP 4027
129.215.212.0/24 M 212
192.168.105.0/24 ATopen 505

In addition, VLAN 952 - called 'phones' - is used to carry the traffic to and from VoIP telephones in AT.

All of this means that, for example, should you want to use a laptop in Appleton Tower or Wilkie on the 192.168.105.0/24 subnet, it must be connected to a network port which has been configured to be on the 'ATopen' VLAN.
